Final answer:
To find the daily amount of dog food you need, divide the fraction 2/4 by 7, will get 1/14 part of the bag.
Step-by-step explanation:
To determine how much food you have to feed the dog each day, you first need to find the daily fraction of the bag of dog food.
Since you have 2/4 of the bag, you can simplify this fraction to 1/2.
To find the daily amount, divide this fraction by the number of days in a week, which is 7
So the daily amount of dog food you need is:
=> 1/2 ÷ 7
= 1/14 of the bag.
